Abstract
A memory structure includes a memory storage element electrically coupled to a control element. The control element comprises a tunnel-junction device. The memory storage element may also comprise a tunnel-junction device. Methods for fusing a tunnel-junction device of a memory storage element without fusing a tunnel-junction device of an associated control element are disclosed. The memory storage element may have an effective cross-sectional area that is greater than an effective cross-sectional area of the control element. A reference element comprising a tunnel-junction device may be used with a current source to fuse a memory storage element without fusing a tunnel-junction device of an associated control element. Methods of making the memory structure and using it in electronic devices are disclosed.
